    • unpackGetExponentUnbiased

      public static int unpackGetExponentUnbiased(float d)

      Extract and unbias the exponent of the given packed float value.

      The exponent is encoded biased as a number in the range [0, 255], with 0 indicating that the number is subnormal and [1, 254] denoting the actual exponent plus BIAS. Infinite and NaN values always have a biased exponent of 255.

      This function will therefore return:

      • 0 - BIAS = -127 iff the input is a subnormal number.
      • An integer in the range [1 - BIAS, 254 - BIAS] = [-126, 127] iff the input is a normal number.
      • 255 - BIAS = 128 iff the input is #POSITIVE_INFINITY, #NEGATIVE_INFINITY, or NaN.

    • unpackGetSign

      public static int unpackGetSign(float d)

      Return the sign of the given float value.

    • unpackGetSignificand

      public static int unpackGetSignificand(float d)

      Return the significand of the given float value.
